z = (x - 500) / 100

1.75 = (x - 500) / 100

175 = x - 500

675 = x

Find the area (shaded) and round to the tenths place if necessary.

fomenos

Answer:

9π - 9

Step-by-step explanation:

Depends on what the question stated was pi (π). The area of the circle is 9(3 squared) * π. the shaded area is the area of the circle - the area of the triangle. The area of the triangle is base * high / 2. If the diameter of the circle (6) is what we use as the base, then 3 would be the high, making the area 9. This means the shaded area would be 9π - 9.
